I think it was the correct decision.  There are no mathematical contexts
in which you want to treat italic f and italic F as the same thing; the
distinction is always meaningful.  Consider the formula for the area of
a trapezoid, A = (B + b)h/2, where B and b are the two bases.

That's the exception.  It's much more common for a relation to
exist between the two cases, such as elements x of a set X,
or the elements a_i_j of a matrix A, etc.  That's like arguing
p and P should not map to each other because polish and
Polish are different.

But if you decide they should _not_ have case mappings, then
you're treating them strictly as symbols, and giving them case
properties is inconsistent.  It should be one or the other.
